Hello, can use this guide - https://www.howtoforge.com/ubuntu-swap-file debiad 7.8 on openvz servers Thank you
On the host server: yes Inside the vm: no Swap inside a vm is defined on the openvz config file of that vm on the host server.
so what should i do if nagios - Service State Information Current Status: CRITICAL (for 6d 15h 43m 5s) Status Information: SWAP CRITICAL - 0% free (0 MB out of 0 MB) - Swap is either disabled, not present, or of zero size. Performance Data: swap=0MB;0;0;0;0 Current Attempt: 4/4 (HARD state) Last Check Time: 02-11-2015 09:28:12 Check Type: ACTIVE Check Latency / Duration: 0.000 / 0.002 seconds Next Scheduled Check: 02-11-2015 09:33:12 Last State Change: 02-04-2015 17:46:54 Last Notification: 02-11-2015 09:28:12 (notification 157) Is This Service Flapping? NO (0.00% state change) In Scheduled Downtime?

Either disable the swap check in nagios as its a false positive (yu dont need swap in a openvz container) or you configure swap in the openvz config for this vm (which basically just simulates swap so that appliactions that check for the existance of swap space think that there is swap).
